To Ml whom it may concern:

Be it known that I, GEORGE C. AVERY, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, haveinven ted certain new and useful Improvements in Eveners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in eveners, doubletrees, and singletrees, and particularly to such as are especially adapted for use upon cultivators.

It consists in an evener comprising a hollow body portion open upon one side and end sections adapted to telescope within said body and clamps extending into the hollow portion of the evener.

It also consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a perspective View of a cultivator provided with an evener, pendant, and singletree constructed in accordance with my invention. Fig. 2 represents a side elevation of an evener. Fig. 3 represents a longitudinal section through the same. Fig.4 represents a transverse section through the said 1 evener, showing the kind of clip or clamp used by me. Fig. 5 represents a side elevation of a pendant constructed in accordance with my invention, and Fig. 6 represents a longitudinal section through the same.

1 in the drawings represents an evener or doubletree, 2 end telescoping sections of the same, and 3 pendants or vertical trees.

In attaching teams to various kinds of implements and vehicles it is often desirable to use eveners and singletrees which are adjustable in length, and especially is this so in using wheel-Cultivators, in which the frame is usually high and the evener or doubletree is correspondingly high and pendants or vertical trees are used in connection with the same. In some cultivators in this class also the parts of the cultivator are so constructed that the cultivator can be widened or narrowed to accommodate them for the cultivation of various kinds of products. My improved evener and pendants are well adapted for use upon a cultivator of this character.

In carrying out the features of my invention I preferably form the evener 1 with a hollow body portion 4, which is preferably made of metal bent upon itself, so as toform a piece of U shapein cross-section. The bodyportioi'i is therefore hollow and open along one side. The telescoping end sections 2 2 are made sufficiently small to enter the hollow portion of the body portion 4. These end sections are preferably made of U -shaped metal pieces open upon one side in a manner similar to the body portion 4. The outer ends of each of the sections 2 2 are preferably closed by an eyepiece or attaching end, as 5. The eye piece is provided with an eye 6 at its outer end, which is adapted to engage the upper ends of the pendants 3 3 in a manner as will be hereinafter described. In order to hold the end sections 2 2 at different positions with in the body portion 4 of the evener, I employ clamps, as 7 7, preferably arranged near each end of the evener. These clamps 7 are made in the form of clips, their free ends being bolted together upon the closed edge of the body of the evener. Each of the clamps is provided with an inwardly-extendin g projection 8, which extends into the hollow portion of the evener and of the telescoping sections 2, its ends being preferably enlarged, as at 9,

and adapted to bear against the inner surface of the telescoping section to more firmly hold the said section in its adjusted positions. In

order to prevent the clamps 7 7 from movin g longitudinally with respect to the evener, I preferably notch the edges of the said body portion at the points where the clamps are applied, the said clamps resting in the said notches, as clearly shown in the drawings. The free ends of the clamps,which are bolted together, are preferably provided with laterally-extending bearing portions, as 10 10, for obtaining a firmer hold upon the evener when the clamps are bolted in place. It will be seen that by this construction the sections of the evener may be adjusted to different widths and can be held in place at any desired point, the clamps taking hold of the material nomatter what their relation to each other. The length of the evener can thus be adjusted to the fraction of an inch and be as firmly held together in one adjustment as in another. The center of the evener is preferably perforated and provided with a vertical bearing, as 11, through which a pivot-bolt may be passed for holding the evener upon the vehicle or cultivator. The pendants 3 are made practically in the same manner as the evener, butare preferably formed with a telescoping section at their lowerends. The body portion 12 of each pendant is made of a U- shaped piece, and a telescoping section 13 is inserted into its lower end and held in place by means of a clamp or clip 14 of similar construction to the clamps 7. The section 13 is also provided with an eye at its lower end to which may be attached the singletrees of a team. The upper end of each of the pendants is provided with a piece 15, having a slightly-curved bearing, as 16, at its upper end. The curved portion of this piece is adapted to hook into the eyes at the end of the evener. The piece 15 is bolted in the upper end of the U-shaped pendant. The upper end of the bearing 16 is preferably perforated,and a cotter-pin or other like fastener may be inserted therein for holding the pendant in position upon the evener. To the central portion of each of the pendants is secured a clip, as 17, which is provided with a bearing 18, which secures the said clip in place and provides a means for attaching the pendant to the frame of the cultivator or other vehicle, as clearly seen in Fig. 1 of the d rawings.

It will be seen that by this construction I am enabled to produce an evener and pendants which can be adjusted to vehicles of different widths and the line of draft from the different pendants can be raised or lowered, as may be found most desirable. I thus sccure a large range of adjustments in these parts and yet obtain great strength no matter what the adjustment. It will be apparent that all kinds of eveners, doubletrees, singletrees, or pendants may be made in this manner without departing in the least from the spirit of my invention.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

1. An cvenercomprising a hollow body portion U shaped in cross-section, telescoping sections in the ends thereof, also U-shaped in cross-seetion, and clamps for securing the sections in place, said clamps extending into the open sides of the body and sections, substantially as described.

2. Double or single trees for teams, comprising a body portion made of material bent in U shape and open along one edge, tele' scoping sections extending into the ends of said body portion, the said sections being also formed of U-shaped material, eyepieces secured in and closing the ends of the telescoping sections, the said eyepieees being provided with attaching-eyes for engaging vertical or horizontal singletrees, and clamps adapted to be applied upon the body portion of the trees for holding the sections in their adjusted positions, substantially as described.

3. In double or single trees for teams, the combination with a hollow body portion open at one edge, of telescoping sections also 1101- low and open at one edge, the said telescoping section extending into the ends of the body portion, attaching-eyes secured to the outer ends of the telescoping sections, clamps for holding the sections in their adjusted positions, the said clamps having inwardly-extending projections adapted to extend into the hollow portion of the parts of the tree and bear against the inner surface of each of the telescoping sections to bind them more securely in place, substantially as described.

4-. In double or single trees, the co1nbination with hollow telescoping sections open along one edge, of clamps 01 clips for holding the sections together, said clips having lateral projections for forming broad bearing-surfaces at their free ends, bolts for securing their free ends together and in wardly-extending projections having enlarged heads, said heads engaging theinner surfaces of the telescoping sections for holding the parts firmly together, substantially as described.

5. A pendant or vertical tree for vehicles, comprising a hollow body portion U-shaped in cross-section, a telescoping section at one end, a clamp for holding the same in place and an eye-engaging piece bolted in the other end of the said singletree and having an upwardly-extending curved end or bearing for engaging the eye of an evener or doubletree, and means at the center of the pendant for securing it to the frame of a vehicle, substantially as described.

6. In double or single trees for vehicles, a main hollow body U-shaped in cross-section, and provided with notches in its edges, end portions telescoping in to the U shaped bodies, and clamps'encircling the body portion in said notches and bearing upon the telescoping end sections, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

GEORGE G. AVERY.
